WILLIAM H. GEORGE, OF DEXTER, IOWA.

DRIVING MECHANISM.

Specification of Letters Patent.

Patentetwaa r fiiiw- Application filed December 10, 1909. Serial No. 532,333?

To all whom it may concern:

Be it known that I, WILLIAM H. GEORGE, a citizen of the United States of America, and resident of Dexter, Dallas county, Iowa, have invented a new and useful Driving Mechanism, of which the following is a specification.

The object of this invention is to provide an improved construction for a hand-motor which may be employed in operating a washing machine or other device.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which Figure 1 is a side elevation of the complete machine. Fig. 2 is a plan of the machine, the levers being removed. Fig. 3 is a crosssection on the indicated line 33 of Fig. 1.

In the construction of the machine as shown the numeral 10 designates a tub carried by legs 11, 12, 13 and 14 and serving in this instance as a support for the handmotor and the devices operated thereby. A bearing plate 15 is mounted horizontally on the bottom of the tub 10. A pendulum 16 is pivoted on and depends from the plate 15 centrally of and beneath the tub. A bracket 17 is fixed to and projects horizontally and radially from the lower portion of the tub 10, and a hand-lever 18 is fulcrumed near its lower end on and is arranged vertically relative to said bracket. The hand-lever preferably is made of metal and is provided with a removable handle 19 on its upper end, which handle is preferably made of wood. A bracket 20 is fixed to and projects laterally from the tub 10 in a plane above the bracket 17, and a lever 21 is fulcrumed at its center on said bracket 20. The lower end portions of the levers 18 and 21 are conjunctively pivoted to one end portion of a pitman 22 and the opposite end portion of said pitman is pivoted to the pendulum 16 at a point between its ends. A pitman 23 is pivoted at one end to the upper end of the lever 21 and is adapted to engage a device to be driven, such as a pinion 24:. In this instance the pinion 30 is mounted on and adapted to turn rotatively an agitator or dolley within the tub. It will be observed that the leverage of the operator on the pitman 22 through the medium of the lever 18 is considerably more than equal.

In practical operation the lever 18 is oscillated manually and effects an oscillation of the lever 22 and reciprocation of the pitmen 22, 23. The pitman 23 acts upon and operates the device or mechanism to be driven adapted to do the Work provided for it. The pitman 22 oscillates the pendulum 16, and stores momentum therein. I Vhen manual operation is relaxed from the lever 18, the pendulum 16 continues to oscillate for a time and acts through the pitman 22 to the oscillation of the lever 21 and continuing reciprocation of the pitman 23. It is the function of the pendulum in this connection to overcome a temporary overload of the pitman 23, and to maintain a uniformity of oscillation of the lever 21.

I claim as my invention 1. A driving mechanism, comprising a suitable support and legs therefor, a hand lever fulcrumed intermediate of its ends on one side of said support, another lever arranged contiguous and parallel to and on the same side of the support with the hand lever and fulcrumed intermediate of its ends to said support, the axis of articulation of the second lever being parallel with and above the axis of articulation of the first lever, pivotal connections between the lower ends of said levers, a pitman pivoted to the upper end of the second lever, means for applying said pitman to a load, a pendulum pivoted to and depending from the central portion of the support, and a pitman forked. embracing and pivoted at one end conjunctively to the lower ends of the levers and pivoted at the other end to and intermediate of the ends of the pendulum.

2. A driving mechanism, comprising a suitable support and legs therefor, a hand lever fulcrumed intermediate of its ends on one side of said support, another lever fulcrumed intermediate of its ends to said support, the axis of articulation of the second lever being parallel with and above the axis of articulation of the first lever, the lower ends of said levers formed with longitudinal registering slots, a pin extending through said slots, a pitman pivoted to the upper end of the second lever, means for applying said pitman to a load, a pendulum pivoted to and depending from the central portion of the support, a nitman pivoted at one end on parallel guide bars to end portions of the the pin in and conjunctively to the lower first bars. 10
